This United States Geological Survey (USGS) general interest publication presents a description of ground water in the U.S. This includes what ground water is, how it occurs, aquifers and wells, ground water quality and what affects it, and the state of U.S. ground water resources. Full description.

This lesson plan will explore the hydrologic cycle and the journey water makes to our glass. Upon completing this lesson, students should know and understand the components of the hydrosphere of Earth, especially the surface and subsurface features, and should be able to prepare a diagram to illustrate the path of their drinking water from the place of precipitation to the tap.

This U.S. Geological Survey (USGS) water resources site provides comprehensive coverage of water related issues, and includes several interactive quizzes and activities for children. Here you will find information on many aspects of water, along with pictures, data, maps, and an interactive center. Topics include: Earth's water, Water basics, Water use, Water Questions and Answers, Activity center, ... Full description.

These interactive exercises are designed to help students learn about river processes like discharge, flooding, and flood frequency. Each activity requires them to make careful observations and measurements, do simple calculations, and answer questions about their work. An interactive feedback and answer checking function checks their work. A Certificate of Completion is available at the end of each ... Full description.

This activity allows students to better understand aquifers and the issues of climate, spring flow, environmental protection, and water use. The activity centers around a constructed ground-water system and contains vocabulary, materials, procedures for two labs, data sheets and information on analyzing the data. Full description.

This web page is a tide and current predictor provided by Dean Pentcheff from the University of South Carolina. The site allows you to select a region, choose the location, and then prepare a customized table of tidal height and/or current speed and direction. Full description.

In this module, students carry out a number of activities that demonstrate the concepts of evaporation, condensation, precipitation, and soil moisture and runoff. The students then construct a terrarium as a way to observe the water cycle as a whole. Immediately following this, students use the Internet to acquire Real Time Data from the Olympic Peninsula in Washington which they can then use to describe ... Full description.

This site contains a series of six posters all relating to water education: wetlands, water use, waste water, navigation, ground water, and water quality. Each poster includes information about the topic as well as related classroom activities. The objective of the water-resources education program is to stimulate interest in and provide a basic knowledge of water resources for students in grades ... Full description.

This database and accompanying report demonstrate the potential of combining observed river discharge information with a climate-driven Water Balance Model in order to develop composite runoff fields that are consistent with observed discharges. This combination preserves the accuracy of discharge measurements as well as the spatial and temporal distribution of simulated runoff, providing a 'best ... Full description.

This program provides scientific research and assessment to evaluate the effects of atmospheric deposition on aquatic and terrestrial ecosystems. A clickable map depicts locations of acid rain monitoring stations by state. This site also contains reports presenting data on acid rain trends and monitoring efforts as well as research performed on acid rain accumulation values. Information is also available ...
